To find this you have to do: (1+2+3+4+5+6+7+8+9+10+11+12)x2
This will give you 78 x 2. The bell will toll 156 times a day.

The measures of the angles of ABC are given by the expressions in the table A( 6X - 1 ) ° B 20° C ( x + 14 ) ° what are the meas

lawyer [7]

Answer:

Step-by-step explanation:

The sum of the angles in a triangle is 180 degrees. This means that in triangle ABC,

Angle A + angle B + angle C = 180

Therefore,

6x - 1 + 20 + x + 14 = 180

6x + x + 20 + 14 - 1 = 180

7x + 33 = 180

Subtracting 33 from the left hand side and the right hand side of the equation, it becomes

7x + 33 - 33 = 180 - 33

7x = 147

Dividing the left hand side and the right hand side of the equation by 7, it becomes

7x/7 = 147/7

x = 21

Therefore

Angle A = 6x - 1 = 6 × 21 - 1

Angle A = 125 degrees

Angle C = x + 14 = 21 + 14

Angle C = 35 degrees.

madam [21]

15% x
100 1.15 X is your variable, your unknown number and 15% has to always be over 100 , Then you have to cross multiply and divide 100 because that is the only number basically you have to just multiply across and divide 100 to make it to the nearest cent you have to round the last two numbers after the decimal Representing money.. Hope this helps!!

Answer:

The answer is $2x^{3}y^{-2}\sqrt{6}$

Step-by-step explanation:

∵ √24 = 2√6

∵ $\sqrt{x^{6}}=(x^{\frac{1}{2}})^{6}=x^{3}$

∵ $\sqrt{y^{-4}}=(y^{\frac{1}{2}})^{-4}=y^{-2}$

∴ $\sqrt{24x^{6}y^{-4}}=2x^{3}y^{-2}\sqrt{6}$
